RPM Airgap vs. non-Airgap?

This is my first attempt at building a street/occasional strip car. I have not run this car or engine before. Good point on the carb changes. Hopefully I can get an ideal test setup but could be interesting none the less.

After talking with FBO on my setup it sounds like I will have detonation issues using crappy 91 octane gas available here in California. Is there a place where I can get 92/93 in Socal? What are you guys doing to help with the low octane issues and detonation problems associateed with it. JB Additives/Boosts/Fuel Mixing etc?

Maybe a new thread on fuels for our loder muscle cars?

I feel your pain with the crappy 91 oct. we have it here in vegas. I have to run about a 35-40% mix of 100oct with 91 on my 9.7:1 318 :sad1:
